ABSTRACT:
A circuit breaker wherein a linkage transmits movements of a manual operating lever to a movable contact for moving the movable contact against a spring bias into engagement with a fixed contact. The linkage is arranged to hold the movable contact in an "ON" position and a releasable latch couples the linkage and the movable contact. A fault detector can effect release of the latch to permit the movable contact to move under the action of its spring from engagement with the fixed contact independently of movement of the linkage and the lever.
